Setting up a node via Docker

Docker (https://www.docker.com/) has become a common way to deploy for testing or production some application server.

Docker is a container system that allows to easily deploy replicable installations of server applications. With Docker, you don't need to set up a host, configure it, download the Elasticsearch server, unzip it, or start the server--everything is done automatically by Docker.

Getting ready

You need a working Docker installation to be able to execute docker commands (https://www.docker.com/products/overview).

How to do it...

1. If you want to start a vanilla server, just execute:

           docker pull docker.elastic.co/elasticsearch/elasticsearch:5.1.1

2. An output similar to the following screenshot will be shown:

   

3. After downloading the Elasticsearch image, we can start a develop instance via:

           docker run -p 9200:9200 -p 9300:9300 -e "http.host=0.0.0.0" -e    
           "transport.host=0.0.0.0"    
           docker.elastic.co/elasticsearch/elasticsearch:5.1...
